Another quacker from our favourite OBE.

A duck walks into a bar and says to the barman, 'Got any bread??'

'No,' replies the barman, 'this is a pub, I serve beer.'

'Oh,' says the duck, 'have you got any bread??'

'I just told you no. This is a pub, I serve beer.'

The duck just sits quietly for a few minutes while the barman serves
another customer. When he comes back the duck asks, 'got any bread??'

'For the last time NO!' shouts the angry barman, 'and if you ask me
again I'm going to nail your beak to the bar!!!!'

The duck thinks for a second,then says, 'got any nails??'

'No.'

'Got any bread???'
